Kubernetes-1.17

Topology-aware service routing (in alpha)
- Locality: defined by user: same node, same rack, same zone, same region
- Two nodes are “local”, if they have the same value for a special label “topologyKey”
- New PodLocator resource (cache of all Pods in the system) with controller
- kube-proxy will create different proxy rules on different nodes
- dns server change (will be in beta): different dns response on different pods

- CSI = Container Storage Interface
